Police are seeking warrants for the arrest of another group of 200 suspects who sat for the Dec 4 police entrance exam, the police commissioner handling the case says.
Pol Maj Gen Adul Narongsak, deputy chief of the Metropolitan Police Bureau (MPB) in charge of the investigation, said police were collecting evidence to seek court approval for the warrants.
The Criminal Court last week issued warrants for the arrest of 51 medical students and a City Hall official in connection with the police exam.

The names of the 51 medical students were not released while the other suspect was identified as Jeerapoj Plaiduang, 45, an official with the Pathumwan district office under the Bangkok Metropolitan Administration's City Law Enforcement Department.
Investigators said the 51 suspects are accused of helping nearly 300 exam candidates cheat.
They are believed to have written down the answers in large letters which they allowed candidates sitting nearby to copy.
The fraud was detected among candidates sitting entrance tests to enter the MPB at Provincial Police Region 7.
Pol Maj Gen Adul said Sunday that police investigators were also probing a similar stunt pulled in another exam conducted under the border patrol police's supervision.
He said it was up to the national police chief to decide whether to annul the Dec 4 exam.
He conceded that if the exam was annulled, it would have far-reaching ramifications for the police force.
MPB chief Pol Lt Gen Sanit Mahathavorn said the incident was grossly unfair to people who took the exam honestly.
